ARTHUR B. WARD, OF MILLINGTON, MICHIGAN.

CHURN.

SPECIFICATION forming part of Letters Patent No. 266,564, dated October24, 1882.

Application nled September 16, 1882.

To all whom it may concern.:

Be it known that I, ARTHUR B. WARD, of' Millington, in thecountyof'lnscola and State of Michigan, have invented new and usefullmprovenients in Ghurns; and I hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specication.

The nature of this invention relates to certain new and usefulimprovements in the construction ofchurns; and the invention consists inthe peculiar construction, arrangement,'and various combinations of theparts, all as more fully hereinafter set forth.

Figure 1 is a perspective view of my improved churn. Fig. 2 is a centralvertical section of the same.

` In the accompanyingdrawings, A represents a. suitable frame, theupper-ends of the standards of which form bearings for the trunnions B,which are secured to the barrel churn-body (l, and which latter isrotated by means of aa cam-bar, properly secured to the top of thecover, there being two or more cam-projections upon the lower side ofsaid bar, While upon the opposite side there are two sets of cams, b c,either of which may be made to engage with the ears F.

In the open end of the churn-body I place an (No model.)

annular angleiron, H, one edge of which is retained in a croze and isheld therein by the compression of the staves, as in the ordinary mannerof securing a head. In the channel formed by this angle-iron I place aring, I, of cork or other suitable packing, Which projects above thechine.

After the milk to be churned has been placed in the churn the cover isput in position and secured by turning down the lever L, which causes anengagement of the cams with the cover and the ears, thus securelylocking the cover in place and forcing the same down upon thepacking,l'ormingaWater-tightjoint. When the packing has become compressed byirequent use, so that the cam-shoulders c do not force the cover downsufficiently, the cam-bar may be moved laterally, soas to cause theengagement ofthe cams b with the ears.

What l claim as my invention is l. ln combination with a churn, C,provided with the ears F, the cover' E, and cam-bar G, provided with aseries of cams upon opposite sides, substantially as set forth.

2. In combination with a churn body, (l, provided With an adjustablecover, E, the annular angle-iron H and packing I, substantially asspecied,

3. A churn consisting of the body C, cover E, cam-bar G, annularangle-iron H, and packing I, adapted to be rotated in a suitable frame,substantially as and for the purposes herein described.

ARTHUR B. WARD.
